It is true that they are neither rivals nor rivals depending on the person's own will some prefer Bitcoin while others prefer gold in which case bitcoin and gold can complement each other. Many bitcoin lovers consider gold to be valuable because it has been proven over a long period of time and is considered a stable form due to its limited supply. Digital assets like bitcoin are ushering in a new era where digital payments and wealth management can be easier and faster.
They would still exist with each other.
I do think that govs would hold onto gold for long enough, while ordinary people would see BTC as a better opportunity in the long run.
With bigger use cases too.
